Kate must love her blue and purple Whistles dress! The Duchess of Cambridge recycles yet another dress at the Olympics Closing Ceremony on August 12, 2012. She wears a $180 Bella dress, which is, of course, sold out. Her love of the line has even caused the brand's website to crash as shoppers hoped to wear the frock of a princess.
